Answer:
1-k^2
Step-by-step explanation:
tan A= sin A/cos A
(sin A)(cos A)(sin A/cos A)=(sin A)^2
(sin A) ^2 + (cos A) ^2= 1
(sin A) ^2=1-(cos A) ^2
(sin A)^2= 1 - k^2
Answer:
Trinomial can not be factored
Step-by-step explanation Equation at the end of step 2 : 4x 2 - 2x - 1 = 0 Step 3 : Parabola, Finding the Vertex : 3.1 Find the Vertex of y = 4x 2-2x-1 Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum)
